For faster measurements with the SA44B, I would
– disable spur reject.
– set your span between 50kHz to 20MHz
– Increase RBW as much as you can.
– Set VBW equal to RBW.
Using Spike, I was able to achieve ~16 sweeps per second with
– 2MHz span
– 3kHz RBW/VBW
– 27MHz center freq
– spur reject disabled
